11.8 Electromagnetic compability of the converter
● FSA – FSG: Use converters with an integrated C2 line filter (-0AF0 in the last block of the
article number)
● FSH, FSJ: Use of an external line filter
– 400-480 V 3 AC: 6SL3760-0MR00-0AA0
– 500-690 V 3 AC: 6SL3760-0MS00-0AA0
Note
If converters without integrated C2 filters or filters other than those listed above are used, the
machine builder or plant engineer must certify that the interference emissions are limited
according to EMC Category C2, at a minimum. Separate line filters for each converter or a
shared line filter for several converters can be used.
11.8.3.3
High-frequency, conducted interference emissions, EMC Category C1
Description
In conjunction with upstream C1 line filters, the converter meets the limits of IEC 61800-3
Category C1 with respect to conducted interference.
Conditions for compliance with the limits:
● TN or TT system with a grounded neutral point.
● Use of shielded motor cables
● Compliance with maximum motor cable length
● Converter operation using the default pulse frequency or with reduced pulse frequency
11.8.3.4
Current harmonics of individual devices
Description
In regard to the adherence to limit values for the harmonic currents, the EMC product standard
IEC 61800-3 for PDS refers to the compliance with standards IEC 61000-3-2 and IEC
61000-3-12. The limit values of these standards apply to devices that are designed for
connecting to the public low-voltage system.
